Reps. Logan Phillips, R-Mounds, and Trey Caldwell, R-Lawton, called on Oklahoma Attorney General Mike Hunter to open an immediate investigation into the recent actions of the stock trading and investing app, Robinhood.

In response to a large online group of retail investors targeting specific securities, Robinhood had restricted trading of the stocks for a full trading day.

“The trading restrictions implemented by Robinhood are a clear example of market manipulation designed to protect big banks and hedge funds,” said Phillips.

The stocks restricted from purchase on included AMC; Bed, Bath and Beyond; Gamestop; Nokia; BlackBerry; Express; Koss and Naked Brand Group. The purchase of these stocks, which had been shorted by Wall Street investment firms, was encouraged on the popular Reddit page “r/wallstreetbets.” Due to the increase in purchase of these stocks among retail investors, the investment firms lost billions on their return, and Robinhood blocked the purchase of the stocks. Limited purchase power was restored the next day, and Robinhood cited “market volatility” as their reasoning for the restriction

“Robinhood can try to hide behind the excuse of ‘market volatility’ as their reasoning for restricting stock purchase, but in reality they were trying to keep the average citizen from winning in a system that favors Wall Street over Main Street,” said Caldwell.

There has been bipartisan demand for an investigation into this matter at the federal level, and the U.S. Securities and Exchange Commission (SEC) released a statement saying they will be “closely reviewing” Robinhood’s actions.
